ABSTRACT OF THE DISCLOSURE: 3-Methyl piperidine is produced in high yields by hy- drogenating 2-methyl glutaric acid dinitrile in the presence of a nickel catalyst. The use of a nickel catalyst, such as finely divided nickel or nickel on a support, promotes the for- mation of 3-methyl piperidine and suppresses formation of the 2-methyl -1,5-diaminopentane which would normally be expected. 3-Methyl piperidine is used as a vulcanisation accelerator and as an additive for lubricating oils; it is also an interme- diate product for the production of nicotine acid.
